OK! I see where you're going with it, and I can absolutely understand why you'd want to go that way. Its like... have you played Project Ozone 2? The stuff with the Chaos catalyst and all that stuff, its like THAT.That is EXACTLY what I would like to see. I also wouldn't mind if the names were ridiculous too, the more expensive it gets. Perhaps fuel would start with wood, then coal, iron, gold, diamond, emerald, (I'm gonna call the ore ridiculousite for now) ridiculousite ore, ridiculousite ingot, ridiculousite block, refined ridiculousite, refined ridiculousite block, purified ridiculousite, purified ridiculousite block, maxiridiculousite blend (purified ridiculousite powder plus nether star), maxiridiculousite alloy (ridiculousite blend smelted in special machine), maxiridiculousite alloy block, infiniridiculousite blend (alloy plus dragon egg), infiniridiculousite alloy (blend smelted in special machine), infiniridiculousite alloy block, and finally Infinity Stone. (infiniridiculousite compressed like nine times) Infinity stone would last for infinity, as the name suggests. Obviously efficiency would go up as the tier goes up, to make actually feasible to automate. 20 tiers, serious gind, and infinite power generation.
You know...
You could probably customise your own power tier progression path using Avaritia, Quadrum, things like that... I mean, its own mod would obviously be better for what you want, but it sounds like something you could try and map out using a combination of mods and MineTweaker first, to see how you find it, give you ideas, things like that. I'm sure certain things can be added as fuels for particular generators... you probably couldn't manage EVERYTHING you want, and it would take a fair old bit of work, but its not beyond the realms of possibility. If you haven't seen it, get yourself a bit of familiarity with MineTweaker, and then have a look at someone's Project Ozone 2 Kappa Mode playthrough (I recommend Krakaen) - you can see what awesome stuff they've done with custom recipes and items there.
